Chain extender yog ib hom khoom siv uas tuaj yeem nthuav cov saw molecular thiab ua rau kom muaj zog

molecular hnyav los ntawm reacting nrog cov pab pawg neeg ua hauj lwm nyob rau hauv linear polymer saw.

Feem ntau siv los txhim kho cov khoom siv kho tshuab thiab kev ua haujlwm ntawm

polyurethane, polyester, nylon thiab lwm yam khoom.

Epoxy saw extender yog cov saw txuas ntxiv uas muaj glycidyl methacrylate (GMA).

Feem ntau siv epoxy saw extenders suav nrog styrene-glycidyl methacrylate, uas muaj

zoo thermal stability thiab muaj peev xwm undergo lub nplhaib-qhib tshuaj tiv thaiv nrog PA6, es

ntshiab lub cev sib xyaw.Nws tseem tuaj yeem siv rau hauv khib nyiab PET rov ua dua tshiab thiab lwm yam.Cov

Kev ua haujlwm ntawm epoxy saw extenders hauv kev hloov kho nylon yog raws li hauv qab no:

1. cuam tshuam rau qhov hnyav molecular thiab intrinsic viscosity

Epoxy saw extenders tuaj yeem hnov ​​​​mob nrog cov amino pawg kawg thiab cov pawg carboxyl kawg ntawm

PA6, thiab tom qab ntawd txhim kho qhov hnyav molecular ntawm PA6.Txawm li cas los xij, gelation tuaj yeem tshwm sim thaum lub sijhawm

cov saw txuas ntxiv cov tshuaj tiv thaiv, yog li nws yog qhov tsim nyog los tswj cov xwm txheej tsim nyog, tshwj xeeb tshaj yog

kub thiab ntsia hlau ceev, tiv thaiv kev sib txuas hauv reactive extrusion.

Lub intrinsic viscosity ntawm PA6 tau nce sai nrog qhov nce ntawm cov saw hlau

Extender.Thaum cov ntsiab lus ntawm cov saw extender nce mus rau ib qho loj feem, lub

intrinsic viscosity ntawm PA6 poob me ntsis.Qhov no yog vim lub davhlau ya nyob twg pawg PA6 tuaj yeem

hnov ​​mob sai sai nrog cov epoxy pawg hauv cov saw txuas ntxiv vim qhov polarity thiab hydrogen

daim ntawv cog lus.Thaum tus nqi ntawm cov saw extender yog nruab nrab, qhov kev faib ua feem ntawm cov saw ntev

molecules nyob rau hauv lub system nce thiab viscosity nce raws li;

Txawm li cas los xij, raws li covcov tshuaj tiv thaiv pib, qhov kawg pab pawg ntsiab lus ntawm PA6 txo qis, thiab kev sib tsoo

qhov tshwm sim ntawmqhov kawg ntawm cov saw hlau molecular raug txo qis heev vim muaj kev cuam tshuam ntawm

thermal diffusionthiab qhov ntev ntawm cov saw hlau molecular, ntxiv rau, ntau cov saw txuas ntxiv

tuaj yeem ua rau ame me ntawm gel nyob rau hauv lub system, uas ua rau kom ib tug txo nyob rau hauv chain extension

efficiencythiab PA6 intrinsic viscosity.

2. cuam tshuam rau cov khoom siv kho tshuab

Cov txheeb ze molecular loj ntawm PA6 tau nce tom qab cov saw txuas ntxiv nrog epoxy saw

Extender, Lub toughness ntawm cov khoom tuaj yeem txhim kho tau zoo los ntawm kev txo qis

crystallinity thiab grain loj. Tsis tas li ntawd, nrog kev nce ntawm qhov ntev ntawm cov saw molecular,

qhov entanglement ntawm cov chains nce, thiab cov saw molecular yog qhov nyuaj rau plam.Hauv

Txoj kev no, qhov cuam tshuam lub zog tuaj yeem nqus tau los ntawm kev hloov pauv ntawm cov qauv molecular

saws thaum nws raug cuam tshuam los ntawm lub ntiaj teb sab nraud.Tab sis thaum lub loj feem ntawm saw extender

Tshaj ib qho kev faib ua feem, tag nrho cov cuab yeej cuab tam raug txo./n

3. Cov nyhuv rheological

Lub melt flow rate (MFR) txo qis nrog qhov nce ntawm epoxy saw extender,

qhia tau hais tias epoxy saw extender thiab PA6 muaj ib tug zoo saw extension cov tshuaj tiv thaiv.

Nrog rau qhov nce ntawm tus nqi ntawm cov saw extender, qhov sib npaug torque nce ua ntej

thiab tom qab ntawd txo qis, vim qhov txheeb ze molecular hnyav ntawm PA6 tom qab cov saw txuas ntxiv

nce, cov entanglements nyob rau hauv cov saw molecular nce, thiab cov yaj viscosity kuj

nce, yog li lub equilibrium torque nce.

Nrog rau lub sijhawm dhau los, PA6 pellet softened, yog compacted thiab melted maj mam, lub

tsis kam ntawm rotor txo, thiab lub zog torque kuj txo.
